Application led December 22, 1921. Serial No. 524,186.

To all whom may concern: f Be it known that we7 'OLIVER Winronn Cno'onsand Emma HARRY Cnooirs, citizens of the United States, residing` at BigCreek, in the county of Fresno and State of California, have inventedne-w and useful Improvements in Dumping l/iine Cars, of which thefollowing' is a specification.

Our invention relates generally to vehicles having bodies capable ofbeing operated to effect dumping` of their contents, and moreparticularly to dumping mine cars.

The purpose of our invention is the provision of a mine car havingaswinglngly supported body mounted f to normally occupya position inwhich the contents of the body are retained therein. and'which 1smovable to effect the dumping of the contents to either side of the car7our invention including mechanism for moving the body to dumpingposition which can be operated 'independently or in conjunction with themechanism of similarly constructed cars.

Ne will describe one form of dumping car embodying our invention andwill then point out the novel features thereof 1n claims.

In the accompanying drawings- Figure 1 is a view showing in sideelevation one form of car embodying our invention. l

Figure 2 is a vertical sectional view taken on line 2-2 of Figure 1.

Referring specifically to the drawings in which similar referencekcharacters refer to similar parts, our invention in its presentembodiment comprises a chassis designated as C and supported for rollingmovement by wheels W. Upstanding from the chassis C at points adjacentthe opposite ends thereof are standards D and D formed with openingsadapted to rotatively receive stub axles 15 formed on the opposite endsof a bucket or body B.

As clearly shown in Figure 2, the body B includes end walls 16 ofsubstantially triangular formation which are rigidly connected by sideand bottom walls-17 arranged in the form of a V to provide reverselyinclined surfaces to facilitate the dumping of the contents to eitherside of the car.

Medially of the ends of the body B a master gear G is formed, and thisgear is of substantially semi-circular formation so as to maintainmeshing relation with respect to an actuating pinion P irrespective ofthe position of the body. The pinion P vis mounted on a squared portion18 of a. drive shaft S so as to be rotatable therewith while at the sametime being capable of movement longitudinally to engage or disengage themaster gear GQ To effect this movement of the pinion P a sleeve'19 isslidably fitted uponthe shaft portion 18 and provided with asquared boreso as to be rotatable with 'the pinion and shaft. `The sleeve 19 isrecessed to accommodate a forl 20 fixed to `o ne end of rod 21 s lidablymounted inthe standardl and pivotally connected at its opposite end tothe lower end of actuating leverV 22. "The lever 22 is fulcrumed betweenand upon ears 23 at the point indicated at 24 with its upper endprovided with a handle 25 adapted to be gripped in actuating the lever.

As clearly shown in Figure 1 the shaft S is rotatably mounted in endbearings 26 and an intermediate bearing 27 all supported on chassis C.@ne end of the shaft S is shown as provided with a crank 28, and itsopposite end with a universal joint 29 to permit of its connection withthe corresponding shaft of a similarly constructed mine car so that byactuation of the crank 28 rotation of the shafts of both cars iseffected so that the shafts of both cars will be operated simultaneouslyand irrespective of the relative position of such shafts.

ln operation, the body B because of its formation normally occupies,under the action of gravity, the position shown in Figure 2 so as toretain the contents of the body therein. VJ ith the pinion l? in meshwith the master gear G., it will be clear that by rotation of the shaftS a corresponding movement is imparted to the pinion to effect rotationof the body B `to cause a dumping of its contents. rThe contents can bedumped to either side of the car depending upon in which direction theshaft S is rotated, that is to say, when the shaft is ro*i tated in aclockwise direction as when viewed in Figure 2 the body will be rotatedto the rightthereby dumping the contents to the left side of the car.

In a train of mine cars so constructed and having their shafts Soperatively connected to each other through the universal joints 29, itwill be clear that when sufficient power is applied to the crank 28 asimultaneous operation of all the shafts can be effected. Assuming thatall of the pinions P are in mesh with their correspondinggearsG adumping of the contents ofall ofthe cars is readily effected.. By virtueof the mechanismior shifting the pinion P, the bodies of any of thecas'otI the train can be operatively connected or disconnected to orfrom the shafts S so that only the desired-cars y Will be dumped.

Although We have herein shown .and described only one form of dumpingmine car embodying' our invention it is to be understood that variouschanges .and modifications may be made herein Without departv ing,`'fron-1; the spirity of the invention and the spirit. and scope of theappended claims.
